This is what Swifties came for.
Taylor Swift pleasantly surprised fans by playing an acoustic version of Calvin Harris and Rihanna's "This Is What You Came For" during her second Liverpool, England Eras Tour concert Friday night.
"Every single time I have an acoustic set, I'm always trying to think of things you might want to hear — maybe things that might be a little bit unexpected," the 34-year-old global superstar explained before revealing the first surprise song of the night. "Let’s see how we did tonight."
Fans erupted in euphoric cheer as soon as she began performing the smash hit. She played a mashup of "This Is What You Came For" and "Gold Rush," which is off her "Evermore" album.
Her second surprise song mashup combined "The Great War" and "You’re Losing Me."
Swift plays two surprise songs every night at her Eras Tour, one usually on guitar and one usually on piano.
The acoustic set allows the "Maroon" singer to dive into her impressive catalog of songs while giving fans something extra to look forward to during her three-hour show.
The 14-time Grammy winner wrote "This Is What You Came For" with her then-boyfriend Harris, now 40. When it debuted in April 2016, she used the pseudonym Nils Sjöberg because she didn't want her name to overshadow the song.
Shortly after they broke up, TMZ reported she was behind the name. Harris later confirmed she wrote the lyrics and contributed some background vocals via an angry rant on X during which he accused her of trying to "tear" him down. (The rant is hidden as he disabled his X account upon learning that the "Karma" hitmaker sang their song in Liverpool).
"I wrote under the name Nils Sjöberg because those are two of the most popular names of Swedish males. ... And nobody knew for a while," Swift recalled during a 2020 interview with Paul McCartney for Rolling Stone.
While it's not usually her top pick to perform, Swift previously played "This Is What You Came For" in October 2016 at the Formula 1 U.S. Grand Prix in Austin, Texas and at a Super Saturday Night performance in Houston in February 2017.
Swift is currently touring Europe before wrapping up the Eras Tour in Canada in December.
Although there was chatter she may extend it again, she confirmed during Thursday's Liverpool performance that the tour will indeed wrap.
